More about the SiteSentry2
Keep your old dial-up remote and add the web to it. Wire the SiteSentry2's meter inputs across the channels your remote already reads, and its relays in parallel with yours. The old remote keeps working, and you gain web control, an independent alarm handler, a clock-driven scheduler, logging, and e-mail and text alarms, for a fraction of the cost of replacing it.
No Java, ActiveX or other add-ons are needed in the browser.
